I hope it turns out that the shot man actually was something to do with the bombing. It's been announced that he definitely wasn't one of the four men identified from CCTV cameras from yesteday's incidents.

"Met Police Commissioner Sir Ian Blair said officers fired after the man was challenged and refused to obey police."   That's a bit worrying - there was a recent trial of two police officers who shot a man who failed to respond to a shouted challenge and turned out to be deaf. And they weren't even sitting on him at the time they shot him, as appears to have been the case in Stockwell.
